Maven release plugin fails : source artifacts getting deployed twice

We are using the maven release plugin on hudson and trying to automate the release process. The release:prepare works fine. When we try to do the release:perform , it fails because it tries to upload a source artifact twice to the repository.

Things that I tried,

  1. removing the profile which does include the maven source plugin from the super pom ( did not work)
  2. specifying the goals on hudson for release as -P!attach-source release:prepare release:perform. Which I thought will exclude the source plugin from getting executed. (did not work).
  3. tried specifying the plugin phase to some non existent phase in the super pom.(Did not work)
  4. tried specifying the plugin configuration, forReleaseProfile as false. ( guess what?? Did not work too)

It still spits out this error.

Any help regarding this will be really appreciated.

Try running mvn -Prelease-profile help:effective-pom. You will find that you have two execution sections for maven-source-plugin

The output will look something like this:

    <plugin> 
      <artifactId>maven-source-plugin</artifactId>       <version>2.0.4</version>       <executions>         <execution>           <id>attach-sources</id>           <goals>             <goal>jar</goal>           </goals>         </execution>         <execution>           <goals>             <goal>jar</goal>           </goals>         </execution>       </executions>     </plugin> 

To fix this problem, find everywhere you have used maven-source-plugin and make sure that you use the "id" attach-sources so that it is the same as the release profile. Then these sections will be merged.

Best practice says that to get consistency you need to configure this in the root POM of your project in build > pluginManagement and NOT in your child poms. In the child pom you just specify in build > plugins that you want to use maven-source-plugin but you provide no executions.

In the root pom.xml:

<build>   <pluginManagement>     <plugins>       <plugin>         <groupId>org.apache.maven.plugins</groupId>         <artifactId>maven-source-plugin</artifactId>         <executions>           <execution>             <!-- This id must match the -Prelease-profile id value or else sources will be "uploaded" twice, which causes Nexus to fail -->             <id>attach-sources</id>             <goals>               <goal>jar</goal>             </goals>           </execution>         </executions>       </plugin>     </plugins>       </pluginManagement> </build> 

In the child pom.xml:

<build>   <plugins>     <plugin>       <groupId>org.apache.maven.plugins</groupId>       <artifactId>maven-source-plugin</artifactId>     </plugin>   </plugins> </build>
